acpi: Add support for WDAT table
This commit lays the groundwork for implementing the ACPI WDAT (Watchdog
Action Table) table specification. The WDAT is a special ACPI table
introduced by Microsoft that describes the watchdog for the OS.
Platforms that need to implement the WDAT table must describe the
hardware watchdog management operations as described in the
specification. See “Links to ACPI-Related Documents”
(http://uefi.org/acpi) under the heading “Watchdog Action Table”.
BUG=b:314260167
TEST=Mock the acpi_soc_fill_wdat function for a specific platform/soc
and enable ACPI_WDAT_WDT in the kconfig. Check if the build passes
successfully.
